Gemini Surfactant Mascula Composition for Volume and Removability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mascara compositions containing wax lead to clumping, uneven application, dryness, smudging, flaking, and difficulty in removal due to tackiness, while wax-free compositions lack desired properties such as body and volume, and have poor buildability and playtime.
Innovation Solution
A low wax or wax-free mascara composition incorporating a gemini surfactant, co-emulsifier, viscosity increasing agent, and film-forming polymers, which provides improved removability, buildability, and playtime, with a balanced ratio of gemini surfactant to co-emulsifier, and includes a film-forming system and water as primary components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If wax is added to mascara composition to provide body and volume, then the mascara provides good body and volume to the lashes, but the tackiness of the wax leads to clumping, uneven application, dryness, smudging, flaking and difficulty in removal
Solution Approach 1:
The patent changes the chemical parameters of the formulation by eliminating wax and introducing a specific emulsifying system with gemini surfactant and co-emulsifier in controlled ratios (1:10 to 1:50), along with film-forming polymers and viscosity increasing agents, to achieve the desired body and volume without the harmful tackiness of wax
Solution Approach 2:
The patent uses a composite emulsifying system combining gemini surfactant with co-emulsifier, and a composite film-forming system with multiple polymers and co-film formers, to create a mascara that provides body and volume through synergistic material combinations rather than relying on single-component wax
2Ease of operation
If wax is eliminated from mascara to facilitate application and removal, then the mascara is easier to apply and remove, but the compositions lose desirably properties and tend to be runnym
Solution Approach 1:
The patent controls the viscosity parameter by adding viscosity increasing agents to achieve a specific viscosity range that prevents the runnym condition, while maintaining the wax-free formulation for ease of application and removal
Solution Approach 2:
The patent employs a composite system combining emulsifiers, film-forming polymers, and viscosity increasing agents work together to provide stability and prevent runnym consistency without requiring wax
3Volume of moving object
If traditional mascara composition is used with wax, then the mascara provides body and volume, but it experiences more flaking or smudging and is difficult to remove
Solution Approach 1:
The patent changes the chemical composition parameters by replacing wax with a specific ratio of gemini surfactant to co-emulsifier (1:10 to 1:50) and incorporating film-forming polymers, which fundamentally alters the film-forming mechanism to reduce flaking and smudging while maintaining volume
Solution Approach 2:
The patent uses water-soluble or easily removable emulsifying systems and film-forming polymers that create a mascara composition designed for easy removal, sacrificing the long-lasting tenacity of wax for improved reliability in terms of clean removal and reduced flaking
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition achieves better body and volume for lashes, reduced clumping, improved ease of removal, and enhanced water resistance, while maintaining smooth and consistent application, outperforming traditional mascaras in tests for smudging, flaking, and uniform coverage.
